A base station transmits downlink control information to a user equipment at a first serving cell of the plurality of serving cells. The downlink control information includes a carrier indicator and a downlink assignment. When the downlink control information includes an aperiodic SRS request that indicates a triggering of an SRS transmission, the base station receives an SRS from the user equipment at the second serving cell. If the first serving cell is a frequency division duplex (FDD) and the second serving cell is a time division duplex (TDD) cell, the downlink control information includes the aperiodic SRS request. If the first serving cell is the TDD cell and the second serving cell is the FDD cell, the downlink control information does not include the aperiodic SRS request."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for transmitting sounding reference signal","description":"A method is provided for receiving a sounding reference signal (SRS) in a wireless communication system.
